wxpayunifiedorderrequest

场景：springboot网页点击缴费，弹出二维码，支付成功后回调服务器，保存订单信息。

1.先导入包，返回二维码链接，采用第三方包qrcode-utils生成图片。

  1.         <dependency>
  2.             <groupId>com.github.binarywang</groupId>
  3.             <artifactId>weixin-java-pay</artifactId>
  4.             <version>4.0.0</version>
  5.         </dependency>
  6.         <dependency>
  7.             <groupId>org.projectlombok</groupId>
  8.             <artifactId>lombok</artifactId>
  9.             <scope>provided</scope>
  10.         </dependency>
  11.         <dependency>
  12.             <groupId>com.github.binarywang</groupId>
  13.             <artifactId>qrcode-utils</artifactId>
  14.             <version>1.1</version>
  15.         </dependency>

2. 在后台获取配置信息，写在yml

3.写个属性类，读取yml文件

  1. @Data
  2. @ConfigurationProperties(prefix = "wx.pay")
  3. public class WxPayProperties {
  4.     private String appId;
  5.     private String mchId;
  6.     private String mchKey;
  7.     private String subMchId;
  8.     private String certPath;
  9.     private String apiV3Key;
  10.     private String privateKeyPath;
  11.     private String privateCertPath;
  12.     private String notifyUrl;
  13. }

 

4.写个配置类，把配置文件属性注入WxPayService

  1. package com.ruoyi.web.controller.onlinepay.config;
  2.  
  3. import com.github.binarywang.wxpay.service.WxPayService;
  4. import com.github.binarywang.wxpay.service.impl.WxPayServiceImpl;
  5. import com.ruoyi.common.utils.StringUtils;
  6. import lombok.AllArgsConstructor;
  7. import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
  8. import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
  9. import org.springframework.boot.context.properties.EnableConfigurationProperties;
  10. import org.springframework.context.annotation.Bean;
  11. import org.springframework.context.annotation.Configuration;
  12.  
  13. @Configuration
  14. @ConditionalOnClass(WxPayService.class)
  15. @EnableConfigurationProperties(WxPayProperties.class)
  16. @AllArgsConstructor
  17. public class WxPayConfig {
  18.     private WxPayProperties properties;
  19.     @Bean
  20.     @ConditionalOnMissingBean
  21.     public WxPayService wxService() {
  22.         com.github.binarywang.wxpay.config.WxPayConfig payConfig = new com.github.binarywang.wxpay.config.WxPayConfig();
  23.         payConfig.setAppId(StringUtils.trimToNull(this.properties.getAppId()));
  24.         payConfig.setMchId(StringUtils.trimToNull(this.properties.getMchId()));
  25.         payConfig.setMchKey(StringUtils.trimToNull(this.properties.getMchKey()));
  26.         payConfig.setKeyPath(StringUtils.trimToNull(this.properties.getCertPath()));
  27.         payConfig.setNotifyUrl(StringUtils.trimToNull(this.properties.getNotifyUrl()));
  28.         payConfig.setSubMchId(StringUtils.trimToNull(this.properties.getSubMchId()));
  29.         // 可以指定是否使用沙箱环境
  30.         payConfig.setUseSandboxEnv(false);
  31.         WxPayService wxPayService = new WxPayServiceImpl();
  32.         wxPayService.setConfig(payConfig);
  33.         return wxPayService;
  34.     }
  35. }

5. 写个实现类WeChatService，实现类实现预支付wxPayService.unifiedOrder(wrequest)

  public WxPayUnifiedOrderResult createUnifiedOrder(SysChargeVoucher sysChargeVoucher, HttpServletRequest request);

  1. package com.ruoyi.web.controller.onlinepay.service.impl;
  2.  
  3. import cn.hutool.json.JSONObject;
  4. import com.github.binarywang.wxpay.bean.order.WxPayMwebOrderResult;
  5. import com.github.binarywang.wxpay.bean.request.WxPayUnifiedOrderRequest;
  6. import com.github.binarywang.wxpay.bean.result.WxPayUnifiedOrderResult;
  7. import com.github.binarywang.wxpay.constant.WxPayConstants;
  8. import com.github.binarywang.wxpay.exception.WxPayException;
  9. import com.github.binarywang.wxpay.service.WxPayService;
  10. import com.ruoyi.system.domain.SysChargeVoucher;
  11. import com.ruoyi.web.controller.onlinepay.config.WxPayConfig;
  12. import com.ruoyi.web.controller.onlinepay.service.WeChatService;
  13. import org.springframework.beans.factory.annotation.Autowired;
  14. import org.springframework.stereotype.Service;
  15.  
  16. import javax.servlet.http.HttpServletRequest;
  17. import java.math.BigDecimal;
  18. import java.util.HashMap;
  19. import java.util.Map;
  20.  
  21. @Service
  22. public class WeChatServiceImpl implements WeChatService {
  23.     @Autowired
  24.     private WxPayService wxPayService;
  25.     @Autowired(required=false)
  26.     private WxPayUnifiedOrderRequest orderRequest;
  27.     @Autowired
  28.     private WxPayConfig wxPayConfig;
  29.     @Override
  30.     public String createOrderInfo(SysChargeVoucher sysChargeVoucher,HttpServletRequest request) {
  31.         WxPayMwebOrderResult result = null;
  32.         try {
  33.             orderRequest.setOutTradeNo(sysChargeVoucher.getChargeBillId()+"");
  34.             orderRequest.setBody("我是商品描述");
  35.             orderRequest.setTotalFee(sysChargeVoucher.getAmount().multiply(new BigDecimal("100")).intValue());//金额需要扩大100倍:1代表支付时是0.01
  36.             orderRequest.setSpbillCreateIp(this.getAddrIp(request));
  37.             orderRequest.setProductId(sysChargeVoucher.getChargeVoucherId()+"");
  38.             orderRequest.setTradeType(WxPayConstants.TradeType.MWEB);// h5网页支付
  39.             result = wxPayService.createOrder(orderRequest);
  40.         } catch (WxPayException e) {
  41.             e.printStackTrace();
  42.         }
  43.         return result.getMwebUrl();
  44.     }
  45.  
  46.     @Override
  47.     public WxPayUnifiedOrderResult createUnifiedOrder(SysChargeVoucher sysChargeVoucher, HttpServletRequest request) {
  48.         wxPayService= wxPayConfig.wxService();
  49.         WxPayUnifiedOrderResult rest=new WxPayUnifiedOrderResult();
  50.         try {
  51.         WxPayUnifiedOrderRequest wrequest = new WxPayUnifiedOrderRequest();
  52.         wrequest.setDeviceInfo("WEB");//设备号
  53.         wrequest.setBody("物业缴费");//商品描述
  54.         wrequest.setOutTradeNo(sysChargeVoucher.getDocumentNo()+"_"+sysChargeVoucher.getChargeVoucherId());//商户订单号
  55.         JSONObject map = new JSONObject();
  56.         map.put("conventionalChargeIds",sysChargeVoucher.getConventionalChargeIds());
  57.         map.put("meterChargeIds",sysChargeVoucher.getMeterChargeIds());
  58.         map.put("temporaryChargeIds",sysChargeVoucher.getTemporaryChargeIds());
  59.         map.put("apportionChargeIds",sysChargeVoucher.getApportionChargeIds());
  60.         wrequest.setDetail(map.toString());//商品详情
  61.         wrequest.setTotalFee(sysChargeVoucher.getAmount().multiply(new BigDecimal("100")).intValue());//总金额|分计
  62.         wrequest.setSpbillCreateIp(this.getAddrIp(request));//终端IP
  63.         wrequest.setTradeType("NATIVE");//交易类型
  64.         wrequest.setProductId(sysChargeVoucher.getDocumentNo()+"_"+sysChargeVoucher.getChargeVoucherId());//商品id
  65.         rest=wxPayService.unifiedOrder(wrequest);
  66.         } catch (WxPayException e) {
  67.             rest.setErrCodeDes(e.getErrCodeDes());
  68.             rest.setErrCode(e.getResultCode());
  69.         }
  70.         return rest;
  71.     }
  72.  
  73.     private String getAddrIp(HttpServletRequest request){
  74.         return request.getRemoteAddr();
  75.     }
  76. }

 

6.点击缴费，触发创建二维码

html

  1. <button type="button" id="erCodeBut" data-toggle="modal" data-target="#myModal6" style="display: none"></button>
  2. <div class="modal inmodal fade" id="myModal6" tabindex="-1" role="dialog" aria-hidden="true">

  6.                 <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
  7.                 <h4 class="modal-title">微信支付</h4>
  8.                 <span id="tips"></span>
  9.                 <span id="wxamount">0</span>元
  10.             </div>
  11.             <div class="modal-body" style="background-color: #00a65a;text-align: center;">
  12.                 <img id="img2" style="width:200px;height:200px;"/>
  13.             </div>
  14.         </div>
  15.     </div>
  16. </div>

JS 

  1.                    var url = ctx + "pay/createQRCode";
  2.                     $.ajax({
  3.                         url: url,
  4.                         type: "post",

  7.                         success: function (result) {
  8.                             if(result.code==0){
  9.                                 $('#erCodeBut').trigger("click");
  10.                                 $('#img2').attr('src', 'data:image/png;base64,' + result.msg);
  11.                                 var  p=$('#propertyUnitName').val();
  12.                                 var  c=$('#customerName').val();
  13.                                 $('#tips').text("尊敬的"+c+"先生/女士，您名下单元："+p+"的物业费用为：");
  14.                                 $('#wxamount').text(result.data.amount);
  15.                             }else if(result.code==301){
  16.                                 alert(result.msg);
  17.                             }else{
  18.                                 alert("生成二维码识别，请重试!");
  19.                             }
  20.                         }
